# One Scan vs CaptainScanner

The clearest difference is review sentiment: CaptainScanner at 100% against One Scan's 26%. CaptainScanner also leads on rating (4.9 vs 4.7) and iOS requirement (16.0 vs 26.0). One Scan's advantage is ratings volume (12K vs 41) and update cadence (every 2 months vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and CaptainScanner sells 3 in-app purchases, starting at $5.99 per year. Whichever you choose, the download price is not the number that matters.
